I have a string, get by Javascript (the content of a div!);
I want to write this string to PHP, because i want a text file with this content!
How is the best way to do this?
Edit[1]: Method Post doesn't works, because i have '<' chars and it erase them (i don't know why)...
Example: I have #include <stdio.h> and when i call echo $_REQUEST just show #include
...
For the Javascript part, I suggest using jQuery.ajax. It could be triggered, for example, when a button is clicked.
$.ajax({
type: "POST",
url: "process_ajax_div.php",
data: { divHTML: $('#yourdiv').html() },
success: function(){ alert('done!'); },
error: function(){ alert('error!'); }
});
For the PHP part (file process_ajax_div.php) you can do something like this:
<?php
$divHTML = $_POST['divHTML'];
// now do whatever you want with $divHTML
?>
POST the string to the server, the simplest way is to add the value to a form on the page and submit it, but you could submit the value via AJAX if you like... here is the simple example.
<div id="mydiv">Hello World</div>
<form method="post" action="myphppage.php" id="myform">
<textarea name="mytext" id="mytext"></textarea><br>
<input type="submit" value="Create File">
</form>
<script type="text/javascript">
document.getElementById("mytext").value = document.getElementById("mydiv").innerHTML();
document.getElementById("myform").submit();
</script>
You could pass the string text via url to the .php file that will process it.
There are many ways to accomplish that, one, very simple, could be:
var text = "some";
var url = "http://myserver/webapp/file.php?content=" + text;
location.href = url;
or with form or with Ajax and so on...
echo htmlspecialchars($_REQUEST);instead, or useheader('Content-type: text/plain');before you echo anything. Then you will see that the '<' chars are actually there. If you try writing to a file (without thehtmlspecialchars), it will work.
